Though sod can be laid during most parts of the year, fall and early spring really are optimal times The temps are cool and the moisture is high. Along with proper timing, a good foundation of graded compost and microbiologic fertilizers help get the green stuff off to a booming start. We suggest a 1" under layer of premium compost and granular fertilizer per application rates. Liquid natural fertilizers can also be applied throughout the seasons to help keep turf at its finest.
